Application filed December 29, 1917. Serial No. 209,466.

To all whom it may concern:

Be it known that I, KAZIMIRZ OWIKLIfI- SKI, a citizen of Russia, having declared my intention to become a citizen of the United States of America, residing at Blue Island, in the county of Cook and State of Illinois,

. have lnvented certain new and useful Improvements in Ship-Protectors, ofwhich the following is a specification.

This invention relates to certain new and useful improvements in ship protectors.

' Theprimary object of the invention is the provision of a protector for ships substan tially surrounding the hull thereof adapted for cushioning the force of impact exerted by a missile such as a torpedo approaching thc'ship. I l

A further object of the device is to'provide protecting means for a hull arranged with a plurality of differently tensioned resilient mounting means, the construction being such that an oncoming missile moving beneath the surface of the water will be unable to strike the hull of the ship for injuring the Same but will be stopped in its progress after the manner of a shock absorber.

A still further object of the invention is the provision of resiliently positioned protectors substantially surrounding the hull of a ship serviceable as buffers in the event of a collision with a boat or dock and being bulletproof for preventing bullets from hitting the hull of the ship.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a top plan view of a ship provided with my device.

Fig. 2 is a vertical transverse sectional view through a side portion thereof.

Fig. 3 is a horizontal sectional view taken upon line III-III of Fig. 2, and

Fig. 4 is a perspective view of one of the brackets employed with the device detached from the hull.

My invention is adapted for attachment upon any usual form of ship and is herein illustrated operatively arranged upon the hull 10 of a ship 11, the said ship having a deck 12 and 'a cabin 13 as well as a forwardly projecting sharpened prow extension 14.

Arcuate armor plates 15 formed of bulletproof metal are arranged resiliently mounted upon the hull 10 substantially surround- Specification of Letters Patent.

ing the same, ably rectangular in form, normally vertically positioned and reaching from a point substantially upon a level with the keel portion 16 of the hull to a point above thewaterline thereof. Mounting brackets 17 are secured in spaced relation upon the hull 1'0 and the extension 14 thereof, each bracket having two horizontally arranged outwardly projecting sockets 18 and posts 19.

A substantially circular bow spring 20, is slidably arranged upon each pair of posts 19 of each bracket 17 adjustably retained upon the post by means of nuts 21 threaded upon the outer end portions thereof while shock absorbing springs 22 encircle the posts 19 and are tensioned between the bracket 17 and the free end portions 23 of said how spring, it being understood that each one of the plates 15 is centrally secured as at 241 to the spring 20.

A socket 25 is centrally arranged within each spring 20, while a helical spring 26 has its pointed ends positioned within the sockets 25 and the upper ones of saidsockets 18 of the adjacent bracket 17. An inwardly projecting socket 27 is carried by each plate 15 in horizontal alinement with the lower sockets 18 of the brackets 17 and coiled springs 28 have their opposite ends secured within the sockets 27 and the adjacently arranged lower sockets 18.

opposite sides of the extension 14 so that the forwardly positioned armor plates have a swinging movement while the other plates 15 are resiliently supported by the brackets 17 for bodily movement relatively of the hull 10 and substantially parallel therewith. It will be understood that when an oncoming missile strikes one of the plates 15, the bow springs 20 will slightly yield as well as the springs 26 and 28, permitting the plate to move inwardly toward the hull, while upon excessive blows struck upon the plates 15, the stronger helical springs 22 will take up the shock through their seating contact with the springs 20 and the inward movement of the plate will be further cushioned and retarded.

Buffer plates may be arranged in this manner substantially surrounding the hull 10, it being noted that the said plates are slightly spaced apart for accommodating the operative movement thereof and a torthe said plates being preferpedo traveling beneath the surface of the Water toward the ship 11 Will have its forward progress stopped by striking one ofthe plates 15 and this will prevent the torpedo from hitting the hull 10. By reasonof the general curvature of the plurality of plates 15 when. assembled, the device offers little resistance to the travel of the ship through the Water although completely serving its purpose of protecting the hull. 10 against inury.

What I claim as new is:

1, In combination with a hull, spaced brackets secured thereto, an outwardly projecting pair of posts carried by each of said brackets, a bow spring for each bracket having its free ,end portions slidably mounted upon the posts of said bracket, an armor plat-e vertically secured centrally .to a plurality of said bow springs, springs encircling said posts contacting the said brackets and the adjacent sides ofsaid springs, regu lating nuts threaded adjacent the free ends of said posts and helical springs between the said brackets and plates.

In combination with a hull, spaced brackets secured thereto, an outwardly projecting pair of posts carried by each of said brackets, a bow spring for each bracket having its free end portions .slidably mounted upon the osts of said bracket, an armor plate vertically secured centrally to a plueflpn em t i racewa h (chise e 9w fi rality of said bow springs, springs encircling said posts contacting the said brackets, and the adjacent sides of said springs, regulating nuts threaded adjacent the free ends of said posts, sockets carried by said how springs and brackets in substantial alinement "with each other and helical springs arranged with their opposite ends secured in the said sockets.

3. In combination With a hull, spaced ra k ts s ur d the to, an ut r ly n jecting pair of posts carried by each of said brackets, a how spring for each bracket haying free end'portions slidably mounted upon the posts of said bracket, van armor plate verticai ,ly secured centrally to a plurality of said o v springs, springs enc rcling said posts contacting the said brackets and the adjacent sides of said springs, regulating nuts threaded adjacent the free ends of said posts, sockets carried by said how springs and brackets in substantial alinement with each other, helical springs arranged wit their opposite ends secured in the said sockets, horizontally arranged alining sockets carried b the said brackets and plates in a plane beneath the atorernentioned sockets and helical springs having their opposite ends secured Within !the said lower sockets.

"In testimony whereof I affix my signature.
